$\bold{\small{\color{green}{Fundamental\:Postulates\:of\: Kinetic\:Theory:}}}$

1. All matter is made up of extremely small particles, which have an independent existence and are called molecules.

2. Molecules of a given substance are similar in all respects.

3. The molecules of a given substance are in the state of continuous, random and haphazard motion.

4. All molecules have a force of attraction between themselves. This force is electromagnetic in nature and depends upon intermolecular space and nature of participating molecules.

5. The intermolecular spaces are least in case of solids and maximum in case of gases.

6. The volume actually occupied by the matter is very large as compared to real volume of the molecules. The difference accounts for the intermolecular space.

7. In case of liquids and gases the molecules are relatively free. It means they interchange their places and also collide with each other, during their course of motion. However, collisions are elastic in nature, that is , molecules do not lose energy during collisions.

8. The kinetic energy of molecules is directly proportional to kelvin temperature. It becomes zero at zero kelvin.

Answer 2

Answer:

Explanation:

this theory is based on the following pastulates .1; gasses are composed of a large number of particle that behave like hard,spherical object in a state of constant. 2; these particle move in a straight line until they collide with another particle or the walls of a container. 3; these particles are much smaller than the distance between particle. most of the volume of a gas is empty space. 4; there is no force of attraction between gas particle or between the particle and the walls of container.
